A team, led by Pan Jianwei at the University of Science and Technology of China in Hefei, has built a strontium optical clock that would lose or gain less than one second over about 30 billion years – more than twice the age of the universe. The clock’s key parameters, known as stability and uncertainty, both surpassed the level of 10 to the power of... https://www.scmp.com/news/china/science/article/3347101/made-china-clock-loses-second-twice-age-universe?utm_source=rss_feed https://www.scmp.com/news/china/science/article/3347101/made-china-clock-loses-second-twice-age-universe?utm_source=rss_feed Sat, 21 Mar 2026 06:00:21 +0000 Ling Xin Ling Xin Chinese researchers have pushed the frontiers of quantum encryption, demonstrating a powerful new way to send secure information over more than 100km (62 miles) of optical fibre – without having to trust the equipment being used. A team led by Pan Jianwei at the University of Science and Technology of China used a pair of individual rubidium atoms, trapped in laser beams at two separate network nodes, as the foundation for their system, according to a paper published in Science this week.

A team led by Pan Jianwei at the University of Science and Technology of China said their superconducting quantum computer, Zuchongzhi 3.2, had reached the fault-tolerant threshold – a point where fixing errors... https://www.scmp.com/news/china/science/article/3337742/chinas-new-quantum-computer-hits-stability-milestone-beating-google-efficiency?utm_source=rss_feed https://www.scmp.com/news/china/science/article/3337742/chinas-new-quantum-computer-hits-stability-milestone-beating-google-efficiency?utm_source=rss_feed Fri, 26 Dec 2025 01:00:18 +0000 Ling Xin Ling Xin For the first time, scientists in China have faithfully recreated a thought experiment proposed by Albert Einstein nearly a century ago, showing that the quantum world behaves in ways the iconic physicist never fully accepted. Pan Jianwei – known as the country’s “father of quantum” – and his team at the University of Science and Technology of China built a device sensitive enough to register the tiny push of a single photon.

Using a programmable quantum processor named Zuchongzhi 2, Pan’s team has simulated an exotic new state of matter where quantum effects are locked into the corners of a material, according to a paper published in the peer-reviewed journal Science on Friday. These corner states are protected by the deep laws of topology – a kind of quantum armour against errors and... https://www.scmp.com/news/china/science/article/3334549/chinese-scientists-create-super-stable-building-block-quantum-computers?utm_source=rss_feed https://www.scmp.com/news/china/science/article/3334549/chinese-scientists-create-super-stable-building-block-quantum-computers?utm_source=rss_feed Fri, 28 Nov 2025 12:07:43 +0000 Shi Huang Shi Huang The year was 2015, and New York University professor Debra Laefer sat at her desk in Brooklyn reviewing yet another stack of research papers on remote sensing. As she scanned the authors’ affiliations, she paused – the same journals that once overflowed with names from American universities and Nasa labs had begun to publish discoveries from Beijing, Wuhan and Shanghai. Over the next few years, the drips became a wave – and then a tsunami.
